All you need to know about DNS outage

In brief, we will explain exactly what a DNS outage is, why you should be worried, why it happens, and, most importantly, can you prevent DNS outages. We have a lot of ground to cover, so let’s get started.

What is a DNS outage?

A DNS outage is a disruption in the DNS service that stops a particular domain name from being resolved to its IP address.

The DNS (Domain Name System) is a network of servers that translate domain names to IP addresses and facilitate the use of the Internet.

We, people, remember domain names, but we need to access the web hosts where their resources are hosted. This is why we need the IP addresses of the web hosts that the DNS translates for us.

If you have a website and you are experiencing a DNS outage, that means that during that time, there is no DNS server that can respond to clients’ queries. The clients won’t get your server’s IP address and won’t receive service until your DNS servers start working again.

Private DNS server – What is it?

What does a Private DNS server mean?

Although most people utilize public DNS services managed by their preferred ISP, anyone can set up their DNS server. Private DNS is a technique that gives the server owner complete control over the IP addresses and network access that are accessible. They are DNS networks that are independent of the Public DNS.

Furthermore, we refer to Private as DNS over TLS (Transport Layer Security) or DNS over HTTPS (Hypertext Transfer Protocol Secure). While utilizing DoT (DNS over TLS) or DoH (DNS over HTTPS), all DNS queries are encrypted. This makes it far more difficult for shady outside parties to monitor your internet activity.
